For my ASRock X470 Taichi board, someone prepared a special BIOS for going back to old versions. I had to first flash that special BIOS and then the flash feature in that BIOS allowed going back to the old BIOS version.
I don't know any method that works with all boards. Maybe
has an idea, he has a thread about BIOS modding here:
About that special BIOS for my X470 Taichi, it's shared in this blog post here:
At the end of that post, there's a pull-down box with the files for download. The special BIOS is the X470 Taichi version "3.60a".
That said... I'm right now back to the newest BIOS with AGESA 220.127.116.11B and I think this time I will stay with the new BIOS. I can't find a difference in performance to the old BIOS. My experimental settings for 3200MHz seem to boot fine.
Maybe that "wall" at 3200 was really a mistake. Right now I'm trying RTT nom, wr, park = 120, 120, 240 and that seems to boot 100% of the time. I had never tried RTTnom 120 before because I've never seen anyone use it with dual-rank.
About my Dimms, they are two sticks of this weird server/workstation memory here:
I can't take screenshots right now but I have a text file with my timings for 3000MHz:
About my 3200MHz problem, now that it seems to boot fine, maybe the problem is just that one of the timings is too tight. While playing around, I got the feeling that the errors don't immediately happen when I'm starting a stress test, only after a while when the Dimms are warm.
